I also upgraded this Blog software to sphpblog-0.4.7.2. The sphpblog upgrade is very pragmatic. I did encounter an issue with the upgrade. The system would default to a month last year rather than today. I just needed to delete the file ( ~blog_entry_listing.tmp ) in the config directory.

Note----Always make a backup of your "config", "content", and"images" folders. It's probably a good idea to downloadthem to your hard-drive. (I would recommend making amonthly backup.)After you have installed to new version, logout and thelog back in. Click on the "Upgrade Comments" link if itappears.

Option 1--------1) FTP the files to a NEW directory on your web server.2) Copy the "config", "content", and "images" folders intothe NEW directory.3) Verify that everything works.4) Delete the old installation.5) Rename the new installation.
